So my 85 iroc 305 tpi is running really rough. Code is maf voltage to high, whether its plugged in or not. It's a vin f car and they are quite spendy. I don't mind buying a new maf if that's for sure what it is, but im just not sure. Hard to explain how it runs, I can usually keep it going but it seems like it missing on several holes. Any advice on replacement or alternatives? I can get a full pull 5.3 for the price of a nos maf and burn off relay. Any advice would be great.
